This is interesting and here is my question:

Taking the above example from Matthias, assume that I have done everything
including installing the bootcode, then I realize I am not happy with the
scheme and I need to change.
How do I wipe the whole thing in one go so that I can start afresh?

gpart destroy ad4 ??

Why is there no sysinstall-style GUI for gpart?
